Controllable Semi-Open Mariculture Cabin System

Abstract

A controllable semi-open mariculture cabin system is provided, including a mariculture cabin, a water inlet mechanism, a filtering mechanism, and a fish outlet pipe. The water inlet mechanism includes a water inlet pipe and a plurality of high-pressure water inlet pipes. The water inlet pipe is located on one side of an upper part of the mariculture cabin. The plurality of high-pressure water inlet pipes are distributed in a circumferential direction of a top of the mariculture cabin. Tail ends of the high-pressure water inlet pipes are connected to jet pipes extending into the mariculture cabin. The filtering mechanism is arranged at the bottom of the mariculture cabin. An outlet end of the filtering mechanism is located in sea water outside. The fish outlet pipe is provided on a cabin wall of the mariculture cabin. A gate valve capable of opening and closing is mounted on the fish outlet pipe.

What is claimed is: 
     
         1 .

         2 . The controllable semi-open mariculture cabin system according to  claim 1 , wherein a water pump is provided on the water inlet pipe, and the water pump is used for pumping a water source. 
     
     
         3 . The controllable semi-open mariculture cabin system according to  claim 1 , wherein water pumps are also mounted on the high-pressure water inlet pipes; the jet pipes are arranged downward vertically along an inner wall of the mariculture cabin; and jet holes are uniformly distributed in the jet pipes. 
     
     
         4 . The controllable semi-open mariculture cabin system according to  claim 1 , wherein the filtering mechanism comprises a frustoconical fine filter screen and an annular sewage sump; the annular sewage sump is provided in an outer circumference of a bottom of the frustoconical fine filter screen; and a sewage outlet of the annular sewage sump is communicated with a sewage pipeline. 
     
     
         5 . The controllable semi-open mariculture cabin system according to  claim 4 , wherein a coarse filter screen is mounted at an opening of an upper part of the annular sewage sump; and a filtering diameter of the coarse filter screen is greater than that of the frustoconical fine filter screen. 
     
     
         6 . The controllable semi-open mariculture cabin system according to  claim 4 , wherein a tail end of the sewage pipeline extends out of the mariculture cabin and is connected to a solid-liquid separator; and a conveying pump is provided on the sewage pipeline. 
     
     
         7 . The controllable semi-open mariculture cabin system according to  claim 6 , wherein the solid-liquid separator is provided with a solid outlet and a liquid outlet; and separated solid waste is discharged from the solid outlet, and water is discharged from the liquid outlet. 
     
     
         8 . The controllable semi-open mariculture cabin system according to  claim 6 , wherein an overflow pipe is provided at an inlet of the solid-liquid separator, and an outlet of the overflow pipe is communicated with the annular sewage sump.
